Green Light for AI: How Cities Are Learning to Predict Traffic and Climate
This week's roundup shows two faces of the modern city: smart traffic signals that talk to vehicles, and a metropolis that spent years investing in infrastructure to protect itself from extreme weather. Both cases offer concrete inspiration for Polish local governments planning their own rollouts.
01 · Transport & AI
Traffic Signals That Think Along With Traffic
Leotek Electronics has put its Interlux AI Traffic Signal System to a real-world test, choosing a smart city lab in the state of Georgia, USA, as its proving ground [1]. This isn't another concept on paper — it's an actual deployment in a living-lab city, where the technology could be measured against real traffic conditions.
The solution combines three layers: signal management, connected-vehicle communication, and AI-driven safety mechanisms [1]. In practice, this means intersections that don't just react to traffic volume, but actually "see" approaching vehicles and can adjust the light cycle before a jam or collision even happens.
The goal of the test extends well beyond the city in Georgia — it's meant to show local governments worldwide what practical implementation of smart traffic control looks like [1]. It's exactly this kind of case study — backed by real results rather than mere promises — that most interests cities facing decisions about modernizing their road infrastructure.
02 · Climate Resilience
A City That Prepared for Extreme Weather Ahead of Time
From real-time traffic management, we move to a longer-term challenge: cities' resilience to climate change. The latest ranking named Chicago the world's best-prepared city for climate turbulence [2]. The key to this position is the "Deep Tunnel" system — an extensive underground stormwater management network — complemented by green infrastructure and careful stewardship of Lake Michigan's resources [2].
That said, this doesn't mean Chicago can rest on its laurels. The city still faces the risk of violent weather events such as derechos — powerful, widespread windstorms [2]. The ranking coincided with the release of the city's updated 2026 green infrastructure strategy, showing that even the top-ranked city treats climate adaptation as an ongoing process rather than a one-off project [2].
For urban planners, this is an important signal: climate resilience doesn't come from a single investment, but from a consistent, multi-year approach combining underground infrastructure, urban greenery, and water resource management.

Two Speeds, One Direction
Smart signals in Georgia and Chicago's climate resilience differ in timescale — one is a test of technology reacting in split seconds, the other is the result of decades of infrastructure investment. Yet they share a common denominator: data and planning as the foundation of modern city management. Whether it's AI-based traffic control or a climate adaptation strategy, both cases show that the cities of the future win through preparation, not improvisation.
Summary
Summary
From smart intersections to underground flood-protection tunnels — this week showed that smart cities aren't a single trend, but an entire mosaic of technological and infrastructural solutions. If you'd like to see similar innovations firsthand, talk to technology providers, and exchange experiences with other local governments, join us at FutureCity Expo — the Smart Urban Technologies Fair.
Invitation
Smart traffic signals or climate-resilient urban infrastructure — both topics will be very much alive at FutureCity Expo, the Smart Urban Technologies Fair. There you'll meet providers of connected-vehicle and AI transport solutions, as well as experts in green infrastructure and climate adaptation. It's a chance to see firsthand the technologies that living-lab cities around the world are only just beginning to test. Reserve your spot and plan your visit today.
